The purpose of the aviation physical examination guideline is not only to determine the physical fitness of the aviation workers but also to treat the underlying diseases of the aviation employees effectively and to carry out the optimal aviation duties. As medical science advances, treatment guidelines for various diseases are rapidly changing, and aviation physical examination guidelines need to be revised accordingly. Therefore, it is necessary to analyze the change trends of the AME guideline around the world and appropriately reflect it according to the situation of Korea. It is also necessary to continue the training of AME who are required to carry out examinations and certificates by these revision guidelines. Therefore, it would be desirable to analyze the education system of the advanced countries including the US and introduce the advantages of these systems into Korean AME education curriculum. Primarily, with the development of the Internet, various online lectures have been developed recently. Therefore, we first aimed to look at the changes in the current AME guideline of the Federal Aviation Administration. Next, we aimed to discuss changes in the course of the AME refresher course. Finally, we would like to suggest some points to be improved by comparing these AME guidelines and educational programs with those of Korea.

Many different Visitor Guide Programs are active in order to explain the park-visitors of the superiority of National Park ecosystems and to make them aware of the importance of national park conservation. One of those VGPs is Nature Observation Trail. In this study, we analyzed the course and program of Sangui Nature Observation Trail in Juwangsan National Park. We suggest new course and interpretation plates to make explorers understand their contents easily.
Hibiscus hamabo (Malvaceae) is a deciduous shrub mainly found in northeast Asia, including China, Japan, and Korea. Due to its limited distribution on Jejudo Island and at several sites in Jeollanam-do in Korea, H. hamabo has been designated as an endangered species by the Ministry of the Environment and has been the subject of several restoration programs. In this study, we quantified genetic variations using double-digestion restriction-associated DNA sequencing technology in 96 individuals of H. hamabo from 13 distinct populations in Korea. We determined 3,352 genome-wide single nucleotide polymorphism loci after stringent filtering processes and analyzed the level of genetic variation within and among populations as well as the population differentiation and genetic ancestry with various assumptions pertaining to the population origin. Our results indicated weak differentiations among populations surveyed in this study but clearly suggested that most of the H. hamabo populations maintain a relatively high level of genetic diversity as evidence of frequent genetic exchanges among populations via outcrossing or sequential gene flows. For a more detailed analysis of the origin of Korean H. hamabo and its demographic history, it will be necessary to expand sampling in China and Japan.
This study was conducted to investigate effective ways to meet social and cultural interest in and needs of gardens and gardening. A total of 191 respondents who answered they were living in Gyeongnam region in the questionnaire were selected: 102 (53.4%) were males and 89 (46.6%) were females. In frequency of garden visits, 45% of the respondents answered they visited gardens once a year. Their preferred companion was family (43.6%), followed by friends/colleagues (24.3%). Their important motives of garden visits included admiration of gardens' scenery and ambience, pleasure in being outdoors, relaxing mentally and physically, and appreciation of plants. Relatively less important motives included understanding or educating about nature and environmental conservation, and interest in garden design and horticulture techniques. In the overall assessment of gardens and gardening, the quality of the establishment, management and operation of botanic gardens and arboreta in Gyeongnam region scored 3.32 scale, which was close to the level of 'fair.' Also, the respondents agreed at 3.91 scale that it was necessary to improve the garden creation, gardening, and garden culture. Meanwhile, many people in Gyeongnam region did not clearly understand differences between garden and public park, also had a very obscure perception of public garden. The results of importance-performance analysis (IPA) indicated that it is necessary to concentrate on directing and developing some programs such as admiration of beautiful and exotic plants, and education on garden culture including garden making and horticultural techniques.
The results of researching on duties of physical therapist, understanding of elderly diseases and policies related with elderly welfare came out from the survey before beginning of education to physical therapists who attended National Elderly Welfare Physical Therapist Workshop during Sep. 11th to 14th, 2007. They have already understood about long-term elderly care insurance from the policy, and responded that those policies will bring more advantage to elders. On contrary, negative response had reason of low service quality. About elderly care system, there were positive answer of appropriate alternatives to support them, but also other critics had opinion of inevitable choice for living conservation. About understanding of elderly diseases, there were more comprehension of diseases as age gets higher, but most did not understand dementia and paralysis. Past experience and process of medical treatment for their disease were such arthritis, paralysis, broken bone, and dislocation of joint. Prognosis of technical training was mostly answered positively, but linking with other related disease programs were not welcomed. Most respondents thought that professional training were needed. The results of understanding diseases during senescent had high percentage of understanding as age and education was high, and it had eye upon statistics of the survey (p < 0.05) Most of those questioned responded that it is appropriate to have six working days per week and eight hours of daily work, however, present wage is not reasonable. Most of those questioned had negative response of work independence, and had an-swered that there should be certificates needed in related fields. For difficulties during work period, they had hardship instituting direction of treatment by lack of program, level of wage, and physical difficulties. Physical therapists averagely wished to have fewer than thirty patients per therapist. After the research, physical therapists who work in those facilities of elderly care systems agreed on policies, though it should not lower service quality. In addition, they were pros to have elderly care system, yet they are still inevitable option to maintain living. For work environment, the period of work was appropriate, but had different opinions for work independence and regular number of patients. Therefore, there should be more organized treatment program that also should be linked to other practical programs at this beginning point of the policy enforcement and the time that many therapists hope to work in elderly care system.
The public-interest direct payment program involves providing direct payments to agricultural producers and rural residents through public funds, premised on performing public functions such as environmental conservation, stable food supply, and maintaining rural communities via agricultural activities. Scientific estimation of crop cultivation areas and production levels is crucial for formulating agricultural policies linked to regulating food supply, which increasingly impacts the national economy. Conducting comprehensive on-site inspections for compliance monitoring of direct payment programs has shown very low efficiency in relation to budget and time. The expansion of areas subject to compliance monitoring and various challenges in on-site inspections necessitate streamlining current monitoring methods and devising effective strategies. As a solution, the application of Remote Sensing technology and spatial information utilization, allowing swift acquisition of necessary information for policies without overall on-site visits, is being discussed as an efficient compliance monitoring method. Therefore, this study evaluated the potential use of remote sensing for improving operational efficiency in monitoring compliance with public-interest direct payment programs. Using satellite images during farming seasons in Gimje and Hapcheon, vegetation indices and spatial variations were utilized to identify cultivated areas, presence of mixed crops, validated against on-site inspection data.

Establishing conservation programs to protect and maintain populations of endangered species are not only a global trend, but also a pursuit endorsed by the Korean Environmental Conservation Act. This study evaluates the feasibility of alternative habitat patches for the endangered butterfly Parnassius bremeri. A portion of habitat of P. bremeri is expected to be fragmented and damaged due to the scheduled construction of the Sangju-Yongduk Highway. A trans fer of the habitat patches of P. bremeri is also scheduled. In order to select an alternative habitat patch, the Mark-Release-Recapture (MRR) method was used to simulate a patch transfer model. The connectedness between habitat are as and the survival of local populations were evaluated for each candidate habitat. It was found that metapopulations with patch distances of <250m showed a 50% connectedness and survival rate in local populations. P. bremeri were expected to migrate at an average distance of 300m. In addition, P. bremeri formed a metapopulation that exhibited intimate patch dynamics that promoted persistence among these patches. Possible candidate habitats including those recommended by local governing bodies were evaluated along with habitats that may counter problems arising from the damage done to the original habitat and habitats that may have a compensatory value equal to that of the original habitat. Based on these criteria, Ansa-myeon township office was selected due to its high scores. This scoring was based on a consideration of a wide range of variables that mark a successful transfer of habitat. These include the amount of funding available, the governing bodies of the possible alternative habitat, and the Expected collaborative effort of local citizens. This decision was collaborated on by incorporating the expertise of various fields of study including biology, ecology, biogeography, ecological engineering, landscape architecture, and social sciences. Therefore, it is suggested that in order to evaluate an alternative habitat for organisms, many social issues as well as ecological issues must be considered.
Objective: A set of microsatellite markers with high polymorphism from Tsaiya duck were used for the genetic monitoring and genetic structure analysis of Brown and White Tsaiya duck populations in Taiwan. Methods: The synthetic short tandem repeated probes were used to isolate new microsatellite markers from the genomic DNA of Tsaiya ducks. Eight populations, a total of 566 samples, sourced from Ilan Branch, Livestock Research Institute were genotyped through novel and known markers. The population genetic variables were calculated using optional programs in order to describe and monitor the genetic variability and the genetic structures of these Tsaiya duck populations. Results: In total 24 primer pairs, including 17 novel microsatellite loci from this study and seven previously known loci, were constructed for the detection of genetic variations in duck populations. The average values for the allele number, the effective number of alleles, the observed heterozygosity, the expected heterozygosity, and the polymorphism information content were 11.29, 5.370, 0.591, 0.746, and 0.708, respectively. The results of analysis of molecular variance and principal component analysis indicated a contracting Brown Tsaiya duck cluster and a spreading White Tsaiya duck cluster. The Brown Tsaiya ducks and the White Tsaiya ducks with Pekin ducks were just split to six clusters and three clusters when K was set equal to 6 and 3 in the Bayesian cluster analysis. The individual phylogenetic tree revealed eight taxa, and each individual was assigned to its own population. Conclusion: According to our study, the 24 novel microsatellite markers exhibited a high capacity to analyze relationships of inter- and intra-population in those populations with a relatively limited degree of genetic diversity. We suggest that duck farms in Taiwan could use the new (novel) microsatellite set to monitor the genetic characteristics and structures of their Tsaiya duck populations at various intervals in order to ensure quality breeding and conservation strategies.

The amount of pollutants from stationary sources of businesses classified into 1-3 type in Gyeongju was found to be 0.70 ton/yr for PM-10, 13.95 ton/yr for $SO_2$, and 37.12 ton/yr for NOx ; with respect to area sources, 1.02 ton/yr for PM-10, 13.44 ton/yr for $SO_2$, and 21.10 ton/yr for NOx ; and with respect to mobile sources 963.91 ton/yr for PM-10, 1415.02 ton/yr for $SO_2$, and 5612.70 ton/yr for NOx. This study surveyed the concentration distribution of PM-10, $SO_2$, and NO2 in the air in around Gyeongju and Pohang, and found that high concentration was mainly distributed around Pohang Steel Industrial Complex and the around of mobile sources. In Gyeongju area, $SO_2$ was predicted to increase from 0.002 ppm in 2006 to 0.005 ppm in 2015, and that of $NO_2$ was predicted to increase from 0.004 ppm to 0.010 ppm during the same period. At this point, practicing guidelines to reduce air pollutants and management plan for environmental pollutants should be devised, and also practicing and management programs to protect the stone cultural properties from environmental pollutants and other chemical, physical, and biological factors should be actively introduced.
As the concern with the creation of environmental problems and regulations about them becomes internationally growing, environmental cooperations with countries concerned are emerging as the first item on the political agenda. In case of South Korea, cooperations with countries in the Asian region is needed urgently. In particular, cooperations with North Korea will be an important factor to reunify the Korean peninsula as well as to solve environmental problems in South Korea. Accordingly, it is necessary to seek feasible alternatives and possibilities of coping with international environment in South and North Korea. This study is limited to literature study based on collecting materials and the testimony of former residents in North Korea. The period of study ranges from May to December in 1992. The research findings show the following environmental problems and alternatives : It is recognized in South Korea that the creation of environmental problems is product of economic development. Currently, the Korean government makes an effort to revise environmental administration and law, to encourage environmental education, and to proceed with environmental technology policies by establishing environmental policies together with economic development plans. North Korea ascribes the cause of environmental problems to colonial exploitation by Japan and the U.S. Environmental pollutants in North Korea is relatively less than South Korea, provisions such as environmental conservation movement, environmental education, and environmental administration and law are not well organized in the country. However, North korea will speed up its economic development to solve economic crises. Therefore, it is expected that industrial wastes, corrosion of nature, and water pollution will result in serious environmental problems. The fields expected to cooperate with South and North Korea are in the following : South Korea may adopt the model of the former East and West Germany and proceed to cooperate with North Korea in public sector as well as private sector. The possible programs are such as academic exchange to conserve environment, joint research in the area of the Demilitarized Zone, conservation of ecosystems around Imjin and Pukhan Rivers, South Korea's support of advanced environmental technology and industrial and financial aid to North Korea. Conflicts between countries concerned in the North East Asian region will be caused by the responsibilities of pollutions because of the seashore development of the Yellow Sea by South Korea and increasing seashore industrial complexes around the Yellow Sea in China, Therefore, it is desirable that the two countries will participate in organizations related to environment. Joint projects between South and North Korea will be as follows : 1. Construction of long-range monitoring system : 2. Investigation of the state of pollutions around the Yellow Sea and alternatives : 3. Construction of joint monitoring system to regulate the movement of pollutants : 4. Cooperation of environmental technology and exchange of information ; and 5. Support of Cooperation of environment in private sector. Efforts to cooperate with North korea is expected to overcome differences between the two countries as well as to encourage unification of the korean peninsula, which will lead to reducing the cost of environmental recovery. These efforts will also contribute to the maintenance for peace and stability on the korean peninsula as well as in the North East Asian region.
